I'd like to use two separate layouts for my aurelia app. Difference between them is that one doesn't have a sidebar. Currently I'm using one layout file defined as below:
<template>
<div class="container">
<router-view></router-view>
</div>
</template>
If an active route needs this sidebar to appear I'm just putting it into its view.
What I'd like to achieve is to add another layout that would have this sidebar by default:
<template>
<require from="../common/elements/sidemenu/sidemenu"></require>
<div class="container">
<sidemenu></sidemenu>
<router-view></router-view>
</div>
</template>
So the question is - how to do this? Is it even possible with an aurelia app to have multiple layouts (or master pages, however you call those)?
Use aurelia.setRoot()
You can manually set up your application by specifying a script with configure instructions in your index.html. Typically, this is set to main.
index.html
<body aurelia-app="main">
In this script you can specify a root view model using aurelia.setRoot('root'). If no argument is provided, the convention is to use 'app'.
main.js
aurelia.start().then(() => aurelia.setRoot());
However, you can inject the aurelia object anywhere in your application, and call the setRoot function at any time to load a different root view model.
home.js
#inject(aurelia)
export class HomeViewModel {
constructor(aurelia) {
this.aurelia = aurelia;
}
doStuff() {
this.aurelia.setRoot('withSidebar');
}
}
One common use case for this is having a login page, and I've created a complete template for this use case that you can review, clone, or fork here: http://davismj.me/portfolio/sentry/

I am trying to add an external application Chameleon onto my react application and for that I have to add the javascript function to my application.
I only want it to be called in specific situations so I don't want to load it in my index.html. I tried adding it to the render function of my component as:
render() {
return(
<div>
<head>
<script type="text/javascript">/* Chameleon - better user onboarding */!function(t,n,o){var a="chmln",c="setup identify alias track clear set show on off custom help _data".split(" ");n[a]||(n[a]={}),n[a].accountToken=o,n[a].location=n.location.href.toString();for(var e=0;e<c.length;e++)!function(){var t=n[a][c[e]+"_a"]=[];n[a][c[e]]=function(){t.push(arguments)}}();var s=t.createElement("script");s.src="https://fast.trychameleon.com/messo/"+o+"/messo.min.js",s.async=!0,t.head.appendChild(s)}(document,window,"TOKEN");
chmln.identify(USER.ID_IN_DB, { // Unique ID of each user in your database (e.g. 23443 or "590b80e5f433ea81b96c9bf6")
email: USER.EMAIL });
</script>
...
...
</head>
</div>
)
}
But the above doesn't seem to work. I tried the same inside a helmet but no luck. Both of them show an error for
SyntaxError: Unexpected token
Is there a way I can load this function in a specific component or do I have to do it in the index.html?
You seem to have a strong misunderstanding of what react is for and how it is used.
1) There should only ever be 1 head element on the page, and it should be in index.html not in the rendered output of a component.
2) Having a component render a <script> tag goes against the point of using react.
What you need to do is import the code you need into your component:
import './path/to/file.js'
And then from there chmln should be available on the window object
window.chmln.identify()
I am working on Vue app that incorporates Vue Bootstrap Calendar, and I would like to be able to override the content of the day cell (handled by the Day.vue component) to add my own custom content inside. My thought was initially to modify the Day component to include <slot></slot> tags and pass in the custom content that way.
The problem has to do with accessing the Day component. To include the calendar in your app, you include the Calendar.vue component, which includes Week.vue, which in turn includes Day.vue. As I understand slots, I have to have the child component (Day.vue in this case) included in the component where I'm passing the data, which means it would need to be included in my own component.
If this is not possible, my other thought is to perhaps modify the library by adding another configuration prop (something like dayCustomContent) to the Calendar.vue that indicates that the Day cell content is custom content, pass that in to Calendar.vue, and then down to Day.vue, and then in the Day.vue template, have a v-if conditional based on this prop that either displays the custom content or the default cell content, something like:
<template>
<div class="day-cell" v-if="dayCustomContent">
...my custom content here...
</div>
<div class="day-cell" v-else>
...default events from my.events goes here...
</div>
</template>
I would probably then need to define a custom component to render whatever custom content I want to display, and somehow include that component within Day.vue.
So to sum up, my questions are these:
1) Is there a way to do what I need with slots?
2) For my second option, am I going down the right path? I'm open to suggestions.
UPDATE: I was able to get this done by adding a boolean customDayContent prop in Calendar.vue like so and passing it down to Week.vue and then to Day.vue:
<template>
...
<div class="dates" ref="dates">
<Week
v-for="(week, index) in Weeks"
:firstDay="firstDay"
:key="week + index"
:week="week"
:canAddEvent="canAddEvent"
:canDeleteEvent="canDeleteEvent"
:customDayContent="customDayContent"
:displayWeekNumber="displayWeekNumber"
#eventAdded="eventAdded"
#eventDeleted="eventDeleted"
></Week>
</div>
...
</template>
<script>
export default {
...
props: {
...
customDayContent: {
type: Boolean,
default: false
}
},
}
</script>
and then in Day.vue, do like I had suggested with v-if:
<template>
<div class="day-cell" v-if="customDayContent">
<custom-day></custom-day>
</div>
<div
class="day-cell"
:class="{'today' : day.isToday, 'current-month' : day.isCurrentMonth, 'weekend': day.isWeekEnd, 'selected-day':isDaySelected}"
#click="showDayOptions"
v-else
>
... existing code goes here...
</div>
</template>
The last part is referencing the CustomDay.vue component referenced in my v-if block. I want the user to be able to define the content of their own custom CustomDay.vue template in their own parent app. However, I'm having trouble trying to figure out how to do that. Following the pattern of including components already in this component, I added this in the components section of Day.vue:
CustomDay: require("../../../../src/Components/CustomDay.vue").default
? require("../../../../src/Components/CustomDay.vue").default
: require("../../../../src/Components/CustomDay.vue")
However, no matter what I try along these lines, I get an error that the relative module was not found. On top of that, I need to add it to the componentsarray only if customDayContent is true. What is the best way to do that? In a watcher or computer property, perhaps? Or another way?
Situation: I have a view where I'm including a fragment with ng-include. The fragment loads perfectly and works as expected when inside view where controller is defined.
My problem is, that when I want to include external component inside the "ng-include" fragment "myView.html", it doesn't show up. When including it inside the main view where the controller is, it shows up and works as expected.
Main view:
<div ng-controller="MyController">
<div data-ng-include src="'views/myView.html'"></div>
<!-- When loaded here, the component shows up -->
<!-- <div id="componentDiv"></div> -->
</div>
Fragment "myView.html":
<div>
<div id="componentDiv"></div>
</div>
The component is loaded inside the "MyController", where "componentDiv" is the "id" of "div" where the component is placed:
var testObj = new TestObj({"container": "componentDiv"});
Trying to do this to be able to use this fragment with full functionality in several places.
Any ideas or suggestions what to look up or try?
IMHO I think that by saying "...to be able to use this fragment with full functionality in several places" you just answered your question. What you need is to build a custom directive and use it in any place you like.
see directive samples e.g. Angular documentation on directives
I am new to web development and building an application using polymer 1.0.4. I am using the page.js routing similar to the example in start kit. Now many of the custom element that I built are using ajax and periodically refresh the data. The problem with page.js routing that It seems it loads all custom elements even if the element is not viewed by user. so all custom elements are loading the data even if it is not needed. my questions:
1- How could I fix this so the the elements load data only when they are viewed by the end users? Should I change the routing to another options like more-routing?
2- if the user filled the data in one custom element , then clicked on link to another element. The data will remains when the user goes back to the first custom element? How could I reset the polymer and html elements in the custom element when the use back to an old view?
Again, I'd recommend https://github.com/PolymerLabs/more-routing Eventually a 'carbon' (if I recall the name correctly) set of components will deal with this, according to the polymer summit videos, but until then this seems the standard approach.
Set up the pages via:
<more-routing-config driver="hash"></more-routing-config>
<more-route name="one" path="/one"></more-route>
<more-route path="/two">
<more-route name="two" path="/:name"></more-route>
</more-route>
Then the menu via:
<more-route-selector>
<paper-menu selected="0">
<paper-item route="{{urlFor('one')}}">One</paper-item>
<paper-item route="{{urlFor('two', {name: 'sup'})}}">Two</paper-item>
</paper-menu>
</more-route-selector>
And then the actual pages via:
<more-route-selector selectedParams="{{params}}">
<iron-pages selected="0">
<section route="one">
<div> Page one </div>
</section>
<section route="two">
<div> Page two: {{params.name}} </div>
</section>
</iron-pages>
</more-route-selector>
I used it when it was under the Polymore repository on github, and the samples above are from such, but it doesn't seem to have changed that much in its new home.
After you've set up the basics, listen for changes on the iron-pages, such as events that are available here. In such listeners, you can load the data for each section in iron-pages. One approach would be to use such listeners to call a method of a custom element, perhaps using a behaviour, that then brings down the data.
Try dna-router. You can create define states and routes in HTML only.
Setup routes by:
<dna-new-state state='home' route='/home'></dna-new-state>
<dna-new-state state='user' route='/user/:id/'></dna-new-state>
Create views by:
<dna-view
state='home'
element='home-template'></dna-view>
You can get all params inside your home-template polymer properties.
var params = this.params

Firstly, the PolymerLabs/more-routing library is a nice alternative to page.js and is quite easy to implement. As this library is more declarative you can do things like:
routes.html
<more-routing-config driver="hash"></more-routing-config>
<more-route name="myRoute" path="/my-route-path/:id"></more-route>
app-element.html
<dom-module id="app-element">
<style>
iron-selector > * {
display: none;
}
iron-selector > .iron-selected {
display: block;
}
</style>
<template>
<more-route-selector>
<iron-selector>
<x-element></x-element>
</iron-selector>
</more-route-selector>
</template>
<script>Polymer({ ... });</script>
</dom-module>
x-element.html
<dom-module id="x-element">
<template>
<more-route id="route" context name="myRoute" params="{{params}}" active="{{activeRoute}}"></more-route>
</template>
<script>
Polymer({
is: 'x-element',
observers: [ '_paramsChanged(activeRoute, params.id)' ],
_paramsChanged: function(activeRoute) {
if (activeRoute) {
// Active route
} else {
// Inactive route
}
}
})
</script>
</dom-module>
Check out the polyfora app in the demo folder of the repository.
Otherwise, to use page.js I would consider:
Remove any auto iron-ajax queries in custom elements;
Pass a state attribute to custom elements;
Add an observer to any state changes within each custom element which triggers a function to run any iron-ajax queries.
As of Polymer 1.4, carbon-route (later renamed app-route) can be used:
https://github.com/polymerelements/carbon-route
https://blog.polymer-project.org/announcements/2016/03/28/carbon-route-released/
https://www.polymer-project.org/1.0/articles/routing.html
Here's an example taken from the polymer blog:
<carbon-location route="{{route}}">
</carbon-location>
<carbon-route route="{{route}}" pattern="/tabs/:tabName" data="{{data}}">
</carbon-route>
<paper-tabs selected="{{data.tabName}}" attr-for-selected="key">
<paper-tab key="foo">Foo</paper-tab>
<paper-tab key="bar">Bar</paper-tab>
<paper-tab key="baz">Baz!</paper-tab>
</paper-tabs>
<neon-animated-pages selected="{{data.tabName}}"
attr-for-selected="key"
entry-animation="slide-from-left-animation"
exit-animation="slide-right-animation">
<neon-animatable key="foo">Foo Page Here</neon-animatable>
<neon-animatable key="bar">Bar Page Goes Here</neon-animatable>
<neon-animatable key="baz">Baz Page, the Best One of the Three</neon-animatable>
</neon-animated-pages>

I'm trying to dynamically include a template into my index.html. The general structure of index.html is:
<body>
<header ng-controller="Main">
<section>
<!-- global stuff -->
</section>
<section ng-include="moduleName + '/views/menubar.html'">
<!-- module-based stuff -->
</section>
</header>
<div id="view" ng-view></div>
</body>
Sample URL
example.com/<app_name>/index.html#/<module_name>[/method_name]
I can't figure out how to update $scope.moduleName when the route changes. My trouble is two-fold:
The header's controller is Main, not the controller associated with the view, so I can't? update $scope.moduleName from the view's controller (because Main and the view's controller are siblings).
In Main, I tried setting a $scope.$on('$routeChangeSuccess',…), but apparently it is not notified of route changes.
I've thought of setting up a $rootScope.$on listener (as described in SO#15355346) for the route change and broadcasting down to children, who then emit back up their route, which is broadcasted back down so it is available to Main. But that seems heinous.
And I would really prefer to keep the header outside of ng-view.
EDIT I noticed that $route.current.scope has an object named with module_name (possibly because the name of the controller associated with the route's module_name is the same). I'm wondering if I might be able to somehow use the name of that object…
It's hard to say what's wrong in your code without the full picture. Things you show look fine to me.
Please see this plunk I've created to display the ability to do it. Take note that you also can extend route objects with custom properties, like moduleName here:
$routeProvider.when('/page1', {
template: 'one',
controller: 'one',
moduleName: 'firstModule'
});
